4. Cr has four isotopes:
Cr 50
Cr 52
Cr 53
Cr 54
A) Determine how many protons, neutrons and electrons each isotope has.
B) The atomic mass reported for Cr is 54.94. What does this tell us about the relative abundance of each isotope? What isotope should be the most abundant?
C) Write the electronic configuration of the Cr, taking into account that studies show that it has a paramagnetism equivalent to 6 unpaired electrons. Determine the quantum numbers for the last electron 4s of Cr.
D) Determine the effective nuclear charges for the following Cr electrons:
---An electron 4s
---A 3d electron
Please try to write everything in an organized maner and legible handwritting.

A 54-card deck has two jokers in addition to the standard 52
cards (13 face values, 4 suits). A joker can be used as any card.
For example, the hand with one king, three queens, and a joker can
count as a full house, because we can choose the joker to act as a
second king.
What is the probability that a random 5-card hand can count as
full house? That is: the hand either is a traditional full house...
